Obtaining disaster response feedback from the epicenter and surrounding areas in the shortest possible time is an important part of post-earthquake emergency work and the most important aspect of emergency decision-making.Work practice has shown that, compared to passively waiting for personnel to report, concrete fire table hidden propane tank act
Waxing/waning of the ice sheets and the associated change in thermohaline circulation have played an important role in global climate change since major continental ice sheets appeared in the northern hemisphere about 2.75 million years ago.In the earliest glacial stages, however, establishment of the linkage between ice sheet development and ocean
Unambiguous and complete determination of the Fermi surface is a primary step in understanding the electronic properties of topical metals and semimetals, but only in a relatively few cases has this goal been realized.In this work, we present a systematic high-field quantum oscillation study up to 35 T on ZrSiS, a textbook example of a nodal-line s
As technology continues to leap forward and innovations advance, the systems of civil aircraft are becoming increasingly sophisticated and complex.Accordingly, there is a rising amount of information to be processed by pilots in the cockpit, increasing their cognitive burden, which weboost splitter significantly threatens the safety of flight.Thus,
In this study, a new method for manipulating energy flow in a 3D vector field is proposed.In this method, an azimuthally-polarized beam with a noncanonical vortex, the X-type vortex, is focused in a high-numerical aperture system.It is found that, instead of the invariance of the energy flow which is characteristic of the traditional vortex (i.e.,
